    An issue was identified in late 2023 with the Zimbra Connector for Outlook (ZCO) software, affecting users who installed Microsoft updates versions 2310 and 2311. Emails sent through ZCO during that period may have appeared blank to recipients. We apologize for any inconvenience this has caused. We have diligently worked to resolve this issue and we’re happy to announce that it has now been fixed. Be sure to upgrade to the latest Outlook version and enjoy seamless email sending through the latest ZCO build.
